Fly uphill in the J an the L and downhill in the G. The L tends to be a good starter 38 because it has the boosted ailerons and dive flaps.
Spend a month or so in the 38 and I'll help you out, look me up.
I don't use the dual throttles most of the time, it can be more of a hindrance.
Dual throttles are good for;
1. Throttling down one engine to compensate for a missing wing, you can fly straight and level with this.
2. Great hammerheads, you can really squeeze every last bit of energy out of the plane and can reverse very quickly.
3. Immersion (AKAK quote).
4. Spin recovery.
5. Making great donuts on the runway.
6. Out of plane, last ditch efforts (cut one engine and roll it hard).
